The Aeronomy of Ice in the Mesosphere (AIM) mission will provide the first detailed exploration of the Earth's unique and elusive noctilucent or night shining clouds that are found literally on the 'edge of space'. Located near the top of the Earth's mesosphere (the region just above the stratosphere), very little is known about how these polar mesospheric clouds form or why they vary. They are being seen at lower latitudes than ever before and have been growing brighter and more frequent, leadi...

|AIM SOFIE and Cloud Composition - NASA/Goddard Space Flight Center Conceptual Image Lab|
The Solar Occultation For Ice Experiment (SOFIE) instrument uses solar occultation to measure cloud particles, temperature and atmospheric gases involved in forming the noctilucent clouds studied by the Aeronomy of Ice in the Mesosphere (AIM) spacecraft. The instrument will reveal the recipe of chemicals that prompt formation of polar mesospheric clouds. It will provide the most accurate and comprehensive look to date of ice particles and chemicals within the clouds as well as of the environment...

|Noctilucent Cloud Animation - NASA/Goddard Space Flight Center Conceptual Image Lab|
Because of their high altitude, near the edge of space, noctilucent clouds shine at night when the Sun's rays hit them from below while the lower atmosphere is bathed in darkness. Also known as Polar Mesospheric Clouds or PMCs, they typically form in the cold, summer polar mesosphere and are made of water ice crystals. In April 2007 the Aeronomy of Ice in the Mesosphere (AIM) Mission was launched with the express purpose of studying noctilucent clouds...
